Thanks Ken. Being you using a compiled from source version. You could re-compile dolphin enabling debug messages in order to provide a more useful backtrace.

I reproduced this in 4.2.2 (Kubuntu 9.04) by right-clicking in my home dir (in the white area, not on a file), clicking "Properties", modifying the permissions and clicking OK. Not 100% reproducible, maybe it depends on files getting changed or added while the Properties dialog is open.

Probably a duplicate of bug 181536 (and quite a few more which can be found by searching crashes with "OrgKdeKDirNotifyInterface" in a comment).

Application: Dolphin (dolphin), signal SIGSEGV

@Frank: could bug 192770 also be related to this? (it seems to be non-reproducible on a updated trunk build) Thanks

(In reply to comment #3)
> @Frank: could bug 192770 also be related to this?

It seems so, but right now I can't reproduce any of these issues in trunk. They never seemed 100% reproducible for me though, so I don't know if this is really fixed or if I'm just unlucky today ;-)

I also got this: bug 193818

Bug 192594 seems to be also related (save dialog on fish using KMail)

*** Bug 200411 has been marked as a duplicate of this bug. ***

*** Bug 200526 has been marked as a duplicate of this bug. ***

To everyone who can still reproduce this crash (I couldn't reproduce it today): there might be some output before the crash which starts with "Items emitted in directory". If you're not running the crashing application from Konsole, this output is in ~/.xsession-errors. It might help if you could paste this output here. Thanks!

[I think bug 181536, where I've once hit the Q_ASSERT(result) in KDirModelPrivate::_k_slotNewItems(), is a duplicate. Probably the segfault occurs if asserts are disabled, but the error output should be there anyway.]

WebSVN link: http://websvn.kde.org/?view=rev&revision=1029200

My fix gets rid of the assert (or crash like in bug 193466) in KFilePreviewGenerator, but that seems unrelated to all the backtraces here mentionning _k_slotNewItems / indexForNode. I still need to find a way to reproduce that crash.

Sorry, Sir, I've been unable to replicate the crash. There were four
similar segfaults prior to my bug report, according to the crash logs I
found. I switched to Thunar for the rest of the day. However, Fedora did
release a glibc update (glibc-2.10.1-5) the following day (2009-10-03). 
The message log is peppered with gvfs-gdu-volume segfaults in libgdu.so
with no visible effects. Don't know why I get Gnome stuff in KDE, but
that's Fedora.

These might be relevant...
http://www.kerneloops.org/submitresult.php?number=771593
http://www.kerneloops.org/submitresult.php?number=771760

I wouldn't consider this a high priority. This instance of Fedora 11 was
upgraded from 8, 9, and 10 all using yum. It's scheduled for conversion
from reiserfs to ext4 with a clean install as soon as I can find enough
room to back up my project files.

Thanks for the reply. You have obviously done your best.

What I was doing when the application crashed:
<In detail, tell us what you were doing  when the application crashed.>

Simply changed directory from one to another. Caught me by surprise.

I'm fishing for dolphin in gdb. My first guess is that my Fedora
installation is not quite right. Although dolphin is running, it started
with the following errors in the same thread:
org.freedesktop.DBus.Error.ServiceUnknown - The name
org.kde.nepomuk.services.nepomukstorage was not provided by any .service
files
  QLocalSocket::connectToServer: Invalid name

Program exited normally. -- Yet dolphin is running. It suggests
debug-install about a dozen programs, including gamin. Gamin is not in
the process tree, nor is nepomuk, which may be the source of these
recent crashes.  Perhaps you might want to close this instance of the
bug due to a corrupt Fedora 11 setup that omitted things that dolphin
occasionally requires and assumes should be already installed. IBK

(In reply to comment #25)
> I'm fishing for dolphin in gdb.

When debugging Dolphin with gdb, it may help to close all Dolphin windows first and then start gdb with

gdb --args dolphin --nofork

Without the --nofork argument, a new process is forked off the one you're seeing in gdb, or another window is opened within an already existing process because Dolphin is a KUniqueApplication.

I have reproced the plasma crash which happened on the same occasion, described in https://bugs.kde.org/show_bug.cgi?id=209862
What I also noticed that after I had changed the icon of /home/user in Dolphin the icon does not get updated in the view. Instead of this "user" (the directory name) gets replaced by a "." That in fact everything went as expected can only be seen after the restart of Dolphin.

degradation of my entire system caused by failed upgrade attempts. The
libdbus segfaults in hal-acl and the gvfs-gdu-volume libgdu segfaults
produced nothing noticeable in KDE at the time. (What if gnome wasn't
installed? Why does KDE invoke those gnome apps?) I had given up
upgrading Fedora fc11 to rawhide because of yum's dependency hell. I
thought perhaps that the most recent version of gcc and its associated
libraries and utilities would fix some libc problems which presented
themselves. I used that partial compiler upgrade to build a 2.6.30.3
kernel, since the Fedora developers were probably frantically preparing
for next month's fc12 rollout ... and thereby hangs a tale. I noticed
the libselinux problems when I set selinux from disabled to permissive,
then couldn't log in. I eventually booted into my 64-bit Slackware
partition, downloaded a few packages and manually installed them in
order to get login, yum, and rpm to work via chroot, then booted the
partially-repaired fc11 and fixed the rest of the problems by forcing
rpm to delete the fc12 packages and installing their fc11 versions via
yum (including rebuilding the kernel with the repaired tool chain). Much
ado over nothing. You wouldn't have been involved if it weren't for the
automatic bug reports. This verbose babbling might help someone else
with similar issues. Lesson? Keep your entire compiler toolchain and
library dependencies in a consistent state, don't do partial package
upgrades. Gcc, g++ and all which that entails has a bizarre and deep
dependency forest. For example, glibc itself has over 3500 dependencies.
It helps to have the same version used to compile each of them.

Thanks to the entire KDE team for their tireless efforts in maintaining
programming excellence throughout such a well-designed, complex user
environment. I've been using it since the late-nineties.

@David: This crash occurs mainly in two situations:

1. Open the Properties dialog, change something (icon, permissions), close it.
2. Click in action in Konqueror's context menu (like open a terminal in the current folder, run some kdesvn actions). There are no crashes for actions run from Dolphin's context menu AFAIK. Don't know if that helps...

I can reproduce the crash quite reliably using the following steps:

a. Open Dolphin, create a folder, enter the new folder
b. When inside the folder, open its Properties dialog (e.g., by pressing Alt+Return)
c. Change the icon of the folder and close the dialog.
d. If it hasn't crashed yet, go back to step b.

It usually crashes after 2 or 3 iterations.

@Frank: Wow, you got steps to reproduce this little monster
I can reproduce the crash using your second set of steps here:

Reproduced, thanks for the precise steps; one needs to change the icon twice indeed, and for the current directory.

The first icon change works but sets refreshItemWasFiltered to true in KDirLister (due to the .directory file being hidden).

And then the second icon change misbehaves because of multiple bugs; wrong directory url emitted (fixed here), in addition refreshItemWasFiltered is still true (aboutToRefreshItem not called) which makes it "add" the item under itself. Fun.
I see, KDirListerCache::aboutToRefreshItem assumes it should go up but this is not true for root items. I think the right fix is to get rid of aboutToRefreshItem altogether, now that we have oldItem+newItem.
Added to my TODO list - no more time today.

Another note to myself: debugging is easier in konqueror otherwise in dolphin there are two kdirlisters involved.

SVN commit 1061513 by dfaure:

Fix crash when changing the icon of the current directory twice.
(for more details about what happened, see bug 190535 comment #74).
The fix was to replace the fragile aboutToRefreshItem stuff with a simple
local var based on the more recently added "oldItem".
The crash is fixed for: 4.4 beta2
CCBUG: 190535

One bug remains though: the dir becomes "." in the dolphin treeview.

SVN commit 1061529 by dfaure:

Fix the subdir being renamed to "." in the dolphin treeview when changing its icon.
 We have to let findByUrl do like slotEntries, and prefer a subdir item with a name
 over a root item with ".". The name doesn't matter for root items, but it matters
 for child items.

Still happens in beta 2, see bug 220162.

I wonder if those crashes were the same backtrace but different steps to reproduce can be fixed with the same commit.. may be there are still special cases that cause the crash...

What I was doing when the application crashed:
This crash happens in any KDE application with an open file dialog. For example
Okular: I click  File -> Open -> Network -> Network Services -> FTP Servers
(url bar shows zeroconf: > _ftp._tcp) -> click on a server named TSW-1(FTP) ->
it shortly shows in url bar: "ftp | tsw-1.local:21" then "ftp | tsw-1.local"
and then crashes immediately.

This looks like a new way to trigger this same bug ?
